When Are Property Taxes Due In Kansas

In Kansas, property tax due dates are established by state law and administered at the county level. Generally, property taxes are due annually, with specific deadlines varying slightly depending on the county. The state mandates a primary due date, but counties may offer installment payment options or penalties for late payments.

Property taxes become due on November 1 of each year. The payment period extends through December 20 without penalty, allowing taxpayers nearly two months to settle their bills. If payments are not received by December 20, penalties and interest begin to accrue.

Many counties provide a two-installment payment option, splitting the tax bill into halves. This option allows taxpayers to pay the first half by December 20 and the second half by May 10 of the following year. However, if the first half is not paid by December 20, the entire amount becomes due immediately and penalties apply.

Some key points about Kansas property tax due dates:

November 1: Taxes become due and payable.
December 20: Last day to pay without penalty.
May 10 (following year): Due date for the second half of installment payments, if applicable.
Late payments after these dates incur penalties and interest charges.

Payment Deadlines and Penalties

Understanding the penalties for late payment is crucial to avoid additional charges. If property taxes are not paid by December 20, a penalty of 3% of the total tax amount is added on December 21. This penalty increases by 1% every month the payment remains delinquent, up to a maximum of 9%.

Interest is also charged on unpaid taxes at a rate of 1% per month from the due date until payment is made in full. These penalties and interest charges serve as an incentive for timely payment and help cover the administrative costs of collecting overdue taxes.

The following table summarizes the deadlines and associated penalties for Kansas property taxes:

Due Date	Payment Requirement	Penalty	Interest
November 1	Taxes become due	None	None
December 20	Last day to pay without penalty	None	None
December 21	Payment late, penalty applies	3% of tax amount	1% per month
January 21	Continued delinquency	4% total penalty	1% per month
February 21	Continued delinquency	5% total penalty	1% per month
March 21	Continued delinquency	6% total penalty	1% per month
April 21	Continued delinquency	7% total penalty	1% per month
May 10	Second half installment due (if applicable)	None if paid on time	None if paid on time
May 11	Second half installment late	3% penalty on unpaid balance	1% per month

Where and How to Pay Property Taxes

Property taxes in Kansas are paid at the county level, typically through the county treasurer’s office or the county clerk’s office. Most counties offer multiple payment methods to accommodate taxpayers, including:

In-person payments at the county treasurer’s office.
Mail-in payments with check or money order.
Online payments via county websites or authorized third-party platforms.
Payments by phone using credit or debit cards.

When paying, it is important to have the property tax statement or parcel number available to ensure proper crediting of the payment. Receipts or confirmation numbers should be retained as proof of payment.

Counties may charge a convenience fee for credit card payments, so taxpayers should verify this information ahead of time. Additionally, some counties provide payment drop boxes for after-hours convenience.

Installment Payment Options

Many Kansas counties offer a two-installment payment plan to ease the financial burden of a lump sum payment. Under this plan:

The first installment (usually 50% of the total tax) is due by December 20.
The second installment (the remaining balance) is due by May 10.

Choosing the installment option requires timely payment of the first half; otherwise, the full amount is due immediately, and penalties may apply.

Taxpayers interested in this option should contact their county treasurer’s office for enrollment procedures and to confirm eligibility, as not all counties may participate or may have specific rules.
